Hi Marek,
Hi! [...]
Am I reading it correctly that the root hub (the one built into the controller) is misbehaving here ?
Note in case of ARC770 the log is very similar except the fact that it goes further to successful device detection.
Applied to u-boot-arc, thanks!
Uh, sorry I didn't get back to you about this. I am wrestling my own issues with the DWC2 USB core :-/ Looks like it doesn't work with USB3340 LPM-capable PHY (it only starts in FS mode), but works with non-LPM-capable USB3300 PHY and starts in HS mode.
Did you figure your issue out by any chance ?
No unfortunately I wasn't able to figure out what's wrong there. For now I parked this activity waiting for response from our hardware guys. I spent way too much time on that and basically need to switch to other high-priority things.
Please let me know what was it, I'd be interested in what went wrong for future reference.
If I ever get that problem resolved I'll let you know.
And thanks for your time anyway, that's much appreciated!
Thanks!
btw can you put me in touch with some guys who work on the DWC2 OTG core? I have a few questions of my own, in particular with regard to the USB3340 PHY, which seems to have issues with the DWC2.
Best regards, Marek Vasut
